The invention discloses a measurement and control device connected with double sets of process layer devices in an intelligent substation and an implementation method thereof. The measurement and control device comprises an intelligent
power module, a master management CPU (
central processing unit) module, a human-computer interaction module and two I / O (input / output) functional submodules. The master management CPU module collects, processes and then retransmits the
data information acquired by the intelligent
power module and the I / O functional submodules to a background monitoring and telecontrol device via an
Ethernet, and the human-computer interaction module is controlled by human-computer interaction
software to display and output the
data information; meanwhile, the master management CPU module receives and retransmits control operation commands to the I / O functional submodules or the intelligent
power module; and the master management CPU module is controlled by master management CPU
software to process two sets of redundant data. By means of flexible
software and hardware configuration, the invention can be adapted to the changing requirements of
engineering applications, solves the problem on how to simultaneously connect the double configured process layer intelligent devices into an independently configured alternate measurement and
control unit, and meets the requirement for the measurement and control device of the intelligent substation.
